Quick overview
- Two inch size Sized for 2 inch heater unions.
- Split design The nut comes in two halves that close around the pipe, so the plumbing does not have to be cut apart.
- Screws included The fasteners that draw the two halves together are supplied with the nut.
- Made for heater repair Listed specifically as a heater repair part rather than a general plumbing nut.
- Saves a replumb A cracked union nut normally means cutting pipe, and a split nut avoids that on a tight heater installation.
- Hand tighten only Union nuts seal on an o-ring, so they are tightened by hand, not with a wrench.

Product details
SuperPro SP0121108020 is a two inch split nut supplied with its screws, sold as a heater repair part.
Why a split nut
Union nuts crack. On a heater that has been overtightened, or on old plastic that has spent years in the sun, the nut is usually the first thing to give. A standard replacement nut has to slide over the end of the pipe, which on an installed heater often means cutting the plumbing apart to get it on. A split nut is made in two halves instead: it closes around the pipe where it sits and the supplied screws pull it together.
Fitting
Clean the pipe and the union o-ring seat before the nut goes on, then draw the halves together evenly with the screws. Tighten the union itself by hand once the nut is assembled. Unions seal on the o-ring, and reaching for a wrench is what breaks the next one.
